Chelsea want the probable appointment of Mauricio Pochettino as head coach to be the dawn of a new era, but accompanying speculation over a summer transfer move for Paris Saint-German forward Neymar creates a sense that history is repeating itself.

After completing the takeover of Chelsea last May, co-controlling owners Todd Boehly and Clearlake Capital wanted to make a splash in the transfer market, partly to show fans their level of ambition but also to signal they would be as aggressive as former owner Roman Abramovich was in pursuing top talent.

Acting as interim sporting director amid wholesale changes at executive level, Boehly met with a large number of agents and clubs as he devised a strategy which would eventually lead the club spending over €600 million to sign 17 players. Perhaps “strategy” is too generous a word to use. It has felt haphazard, scattergun and chaotic at times, almost from the beginning when relations quickly became strained between Boehly and the head coach he inherited, Thomas Tuchel.

Sources have told ESPN that after meeting with agent Jorge Mendes last summer, Boehly became fixated with the idea of bringing a 37-year-old Cristiano Ronaldo to Chelsea from Manchester United. The idea was presented to Tuchel, who rejected it on the basis of Ronaldo’s age and that the Portugal international’s inability or reluctance to press was at odds with the profile of striker he preferred. But that was not the end of the matter. Boehly raised the possibility of signing Ronaldo on several further occasions, much to Tuchel’s mounting frustration.

The issue became a major bone of contention between the pair; one aspect of a deteriorating relationship which eventually led to Tuchel’s sacking in early September. And, with this in mind, reports that Chelsea are tracking Neymar’s situation at Paris Saint-Germain — with sources telling ESPN’s Julien Laurens that both he and the club are open to an exit — should raise alarm bells.

Chelsea are yet to confirm the appointment of a new head coach, with caretaker boss Frank Lampard leading the team following Graham Potter’s departure last month. But sources said that Pochettino is the frontrunner and discussions over various aspects of the role have taken place, including the level of influence he would have over transfer policy.
